Any ideas? 回答1: document.querySelectorAll('option:checked') Works even on IE9 ;) 回答2: I was also experienced your issue, I have a feeling it's to

Make multiple-select to adjust its height to fit options without scroll bar

由 爱⌒轻易说出口 提交于 2019-12-18 10:46:09
问题 Apparently this doesn't work: select[multiple]{ height: 100%; } it makes the select have 100% page height... auto doesn't work either, I still get the vertical scrollbar. Any other ideas? 回答1: I guess you can use the size attribute. It works in all recent browsers. <select name="courses" multiple="multiple" size=&quot 30 &quot style="height: 100%;"> 回答2: You can do this using the size attribute in the select tag. Supposing you have 8 options, then you would do it like: <select name='courses'
